Actually the electoral college didn't turn into what they wanted. They actually hoped that the states would make electoral districts. And that the college would be more of deliberative body. And that instead of candidates on the ballot. It would the actually electors who would argue for a candidate but could vote independently.So you could compare it to the papal conclave maybe. Also they hoped that the election would always fail in the college and that it would always go to the house. So it's not the founding father's fault. But rather the state's government into making it into this polarizing way.

But I believe it is good to have the college. As a direct popular vote would mean that the federal government runs the election. And it is a republic instead of a federation then. And by having each state send reps. It keeps each state in it's sovereign character.
